Reset all after Trial and before purchase licences

Reset all after Trial and before purchase licences

Hi,

I created an account on Zoho One to test the Trial.

I made some tests with CRM and Project example.

Now I want to purchase Zoho One for my company.
How to I reset all content and module of Zoho before purchase licences?

When I purchase, are all data deleted?

Thanks,

Emmanuel Dessy.
